Kinship,Camaraderie and Contestation: Fāṭimid Relations with the Ashrāf in the Fourth/Tenth Century.     

Shainool Jiwa 《Al-Masaq: Islam & the Medieval Mediterranean》2016,28(3):242-264

The founding of the Fā?imid caliphate across the southern Mediterranean, and then in Egypt, Syria and the ?ijāz at the turn of the fourth/tenth century, necessitated its negotiation with the ashrāf, those who claimed lineal descent from the Prophet Mu?ammad, and who by this time had gained significant influence as a social class based on their charismatic descent. While other dynastic powers fostered relationships with various members of the ashrāf, the Fā?imid–ashrāf dynamics were distinctive in that the Fā?imids legitimised their rule as Ismā?īlī Shī?ī imām-caliphs, based on their claim of descent from the Prophet Mu?ammad, and as the sole successors to his authority and leadership over the Islamic world. Consequently, Fā?imid–ashrāf relations were permeated by fraternal camaraderie as well as by competing contestations based on their shared claim to Prophetic lineage.  相似文献

Danica G. Hays  Rebecca E. Michel  Hannah B. Bayne  Anita A. Neuer Colburn  Jayne Smith Myers 《Journal of College Counseling》2015,18(1):49-65

Relationship violence is a salient concern on college campuses today, and psychoeducational groups may be an appropriate prevention format. This article describes a study measuring the impact of college student participation in the HEART (Help End Abusive Relationships Today) program, a series of group sessions designed to increase knowledge and awareness of relationship violence. Findings indicated significant changes for group participants postintervention. Implications and recommendations for college counselors are discussed.  相似文献   

A multi-criteria approach for the group assessment of an academic course: A case study     

《Studies in Educational Evaluation》2015

The present paper aims at proposing a structured methodology to evaluate the results of an academic training course addressed to postgraduate students. The evaluation process intends to identify the efficacy of an education course by means of a comparison between the general objectives and the results expected by the students. Since the evaluated aspects by the students, detected by means of questionnaires, are both quantitative and qualitative, the proposed methodology is based on the analytic hierarchy process (AHP). In order to facilitate the evaluation process, answers have been modelled by means of linguistic variables. In particular, different evaluation scales have been used and each one is characterized by different levels associated to different fuzzy numbers.  相似文献   

可行能力贫困:阅读困难群体的实质性特征     

王瑛琦 《图书情报工作》2016,60(10):11-16

[目的/意义] 旨在厘清"阅读困难群体"的研究对象,分析产生阅读困难问题的原因,提出解决这些人阅读困难问题的策略。[方法/过程] 引入经济学中分析贫困问题根源的"可行能力方法"分析阅读困难群体的问题,从人的能力发展的角度考察阅读困难产生的原因,从而提出解决策略。[结果/结论] 可行能力贫困是阅读困难群体的实质性特征,可行能力贫困产生的原因在于阅读困难群体的"内在性"阅读困难、"结构性"阅读困难以及"生命敏感期"的脆弱性。增强阅读困难群体选择的"能力"与"机会"是扩展可行能力的关键,也是未来图书馆解决阅读困难群体问题的方向。  相似文献

研究生公选课程分组讨论教学的规则设计、组织与有效实施 ——澳大利亚新南威尔士大学(UNSW)研究生公选课程教学经验的借鉴     

蒋辉宇 《安庆师范学院学报(社会科学版)》2019,38(4):114-120

澳大利亚新南威尔士大学的教师通过对学生循环提问与交叉提问的方式,事实上组织起了一场以研究生个人为参与主体的课堂讨论,该课堂讨论通过对研究生讨论表现实时计分的方式凝聚了学生课堂注意力,同时也有效控制了讨论秩序,其教学经验值得我国借鉴。然而,由于两国研究生公选课程人数及国民性格的较大差异,澳洲的教学经验不能在国内同类课堂完全直接适用。有必要进行针对性改造、变通。在改造后的分组讨论模式中,由教师实时记录各讨论小组的发言、提问及评论质量,并通过科学的分数构成及相关规则将各小组成员的个人总评成绩进行具体量化,同时通过小组内部及小组之间的双重竞争机制有效保障研究生个人持续性积极参与分组讨论的全部环节。  相似文献
